البلورات الفوتونية هي أوساط دورية قليلة الضياع للطاقة تستخدم للتحكم بالضوء يرتكـز عملهـا على دورية قرائن انكسار الأوساط الجهرية المكونة لها. و تستخدم لدراسة هذه البلورة نظرياً معادلات ماكسويل، غير أن إيجاد الحلول العامة لهذه المعادلات تحليلياً أمر صعب لأننا نتعامل مع متجهات، لذلك نلجأ إلى الحلول العددية عند حساب العصابة الفوتونيـة الطاقية PBG و معاملي الانعكاس و النفاذية.
Photonic crystals is a low-loss periodic medium with periodic changes of refractive index, which is used to control the light. Theoretically, Photonic crystals can be studied using Maxwell equations, but it’s difficult to find a general analytical solution for these equations, since we are dealing with vectors. So we resort to the numerical solutions for Maxwell’s equations to calculate the reflection and transmission coefficients and the Photonic band gap.

There has been much interest in photonic and spectroscopic devices that are
useful for controlling transmission and reflection coefficients such as multilayer
thin films, photonic crystals, and various Bragg structures in the form of
molds or multilayer thin films.
Gadolinium gallium garnet Gd3Ga5O12 (GGG) co-doped with chromium and
neodymium have attracted attention as an active material for high power solid state
laser.
In this work, three new compounds of benzoxazine monomers were
synthesized based on (phenol, hydroquinone, 2-naphthol) and
triethoxysilyl propyl amine (TESPA) and paraformaldehyde. (TESPA)
were used to study its effect on the thermal stability of
polybenzoxazine
resulting from the ring opening polymerization of prepared monomers.
In this work, several samples of poly(propylene itaconat ortho
phthalate) based on itaconic acid and 1,2-propylene glycol were
prepared by polycondensation.
Fifty eight isolates of lactic acid bacteria were obtained from different
local fermented foods. Isolates were identified using microscopic, cultural and
biochemical tests using API strips. Results showed that 44.83% of the isolates
were rod shape
d and 55.17% belonged to cocci bacteria.
